Class Jacket Designs

In Argentina, at least the area where I lived, graduating classes all raise money and get jackets. It's a huge deal, because so few kids make it into a graduating class, and many of them never actually graduate (but, for some reason, they still get the jacket...).
I designed my own class' jacket (maybe I'll post a pic some day), which was far more unique (and a bit more expensive, too) than this one, which my younger brother's class asked me to design. They gave me browns, black and white to work with because they were the largest graduating class in the history of their town, and consequentially, couldn't agree on actual colors. Since their uniform is maroon (nasty, I know), I took the liberty of using it for the accents. They also stressed to me that they needed something simple that would be affordable and long-lived. These are a few of the ones I came up with.
Any thoughts?
